The flower-girl Glycera was so skilled in varying the arrangement and combination of her flowers, that out of the same kinds she produced a great variety of bouquets; so that the painter Pausias, [1] who sought to rival the diversity of her art, was brought to a standstill, for he could not vary his painting so endlessly as Glycera varied her bouquets. Even so the Holy Spirit of God disposes and arranges the devout teaching which He imparts through the lips and pen of His servants with such endless variety, that, although the doctrine is ever one and the same, their treatment of it is different, according to the varying minds whence that treatment flows. Assuredly I neither desire, nor ought to write in this book anything but what has been already said by others before me. I offer you the same flowers, dear reader, but the bouquet will be somewhat different from theirs, because it is differently made up.
